Last updated on July 19, 2024 4:36 am Details


In this review post we’re going to be discussing the PreSonus Quantum 26×32 Thunderbolt 2 Audio Interface, including an overview of its unique features.

Product Description

PreSonus’ fastest and best-sounding audio interface; takes advantage of the recording; up to four Quantum interfaces can be stacked for higher I/O counts; expandable via ADAT Optical; integrated software control, including recallable preamps, line-level switching, output encoder control assignment, headphone routing, and talkback and monitoring options; DC-coupled analog outputs can provide control voltage to external analog equipment, controlled by a DAW plug-in; peripherals, such as hard drives and displays, can be chained via Thunderbolt; includes Studio Magic Plug-in Suite.

A great choice for a wide variety of recording environments, the 26×32-channel Quantum is PreSonus’ fastest and best-sounding audio/MIDI interface, taking advantage of the high-speed Thunderbolt 2 bus and a no-frills, direct-to-DAW (no DSP added) signal path to achieve extremely low latency. Cutting-edge 24-bit, 192 kHz converters with 120 dB of dynamic range and PreSonus’ recallable XMAX microphone preamps combine to deliver superb audio quality. For more I/O channels, simply stack up to 4 Quantum interfaces via Thunderbolt to create a monster 96×96 system. Using the included Studio One Artist DAW or UC Surface control software, you can remote-control the preamps and many other features. To top it off, Quantum owners get the Studio Magic plug-in suite free and can upgrade to Studio One Professional for 50% off.

Our Verdict

PreSonus made a daring step by foregoing the built-in mixer in order to focus on low-latency functioning, and in my opinion, it was the correct one. With the exception of PCIe cards, they’ve reached low-latency performance that is currently unequaled by any interface I’m aware of, so if you have a computer new enough to support Thunderbolt 2 ports, you’ll almost certainly have no need for monitoring solutions. There can be no better way to reply to the criticism leveled about Studio 192 than to create an interface that inherits all of that product’s many positive attributes while eliminating all of its flaws in one fell swoop. Bravo.

The Quantum from PreSonus combines unequaled low-latency performance and ease of use with excellent sound quality and unlimited expansion potential. In a nutshell, it’s fantastic!
